Data Type Solution in CPP

This Page Contains the Solution in CPP Programming Language for the Day 1 : Data Type, Code Challange of the HackerRank 30 Days of Code.

#include <iostream>
#include <iomanip>
#include <limits>

using namespace std;

int main() {
    int i = 4;
    double d = 4.0;
    string s = "HackerRank ";

    // Declare second integer, double, and String variables.
    int i2;
    double d2;
    string s2;

    // Read and save an integer, double, and String to your variables.
    string tmp;

    getline(cin, tmp);
    i2 = stoi(tmp);

    getline(cin, tmp);
    d2 = stod(tmp);

    getline(cin, s2);

    // Print the sum of both integer variables on a new line.
    printf("%i\n", i + i2);

    // Print the sum of the double variables on a new line.
    printf("%.1f\n", d + d2);

    // Concatenate and print the String variables on a new line
    // The 's' variable above should be printed first.
    cout << s + s2 << endl;

    return 0;
